Ankit Patel CHEM 199 Assignment II: Outline Neural Development and Loss I. Stages of Neural Development A. Proliferation- Cells specified for nervous system (but not neurons) B. Migration- Cells leave neural development and go to their specific locations C. Differentiation- Cells become a specific type of neurons (this continues even after birth); synapse compete with one another to reach specific parts of the body (such as muscles) D. Process Withdrawal- After one synapse has reached the specific muscles, all others stop growing E. Myelination- Axons of the neurons are wrapped with myelin II. Types of Neurons and when they develop A. Motor Neurons 1. First neurons to be formed 2. They are functional even before the synapse is formed 3. This is not influenced by the environment B. Later neurons become more and more influenced by the environment they are in III. Part of the brain and when the neurons develop A. Cerebellum 1. Help with motor skills 2.
